It seems getting a celebrity to inadvertently retweet a picture of a notorious public figure is still not getting old.

This time, Lord Alan Sugar may have fallen foul of a prankster by sharing an image of an infamous Liverpudlian bodybuilder.

According to the Liverpool Echo, Lord Sugar obliged when Twitter user Callum Waters asked him to retweet a pic of his "dad and his mate", supposedly after they had bought two copies of Sugar's new book Unscripted.

The mate in question appears to be Akinwale Arobieke, a bodybuilder who is subject to a court order that bans him from "touching, feeling or measuring people's muscles", The Mirror reported.

Arobieke is well-known in his native town after being handed a Sexual Offences Prevention Order in 2006. Last year, he was described by his own lawyer as "a modern-day bogeyman". Arobieke has never been convicted of a sexual offence and has said his notoriety has led to a "witch hunt" against him.

Lord Sugar's retweet, at 7.20pm last night, was still visible on his page this morning, with hundreds of retweets and shares. The person behind the picture - @callumw8 - seems to have made his tweets private since last night.
